1 Claim. 1

This invention relates to, and it is an object to provide, a childsswing of novel construction.

Another object of the invention is to provide a childs swing arranged sothat it not only amuses children, but provides desirable exercise in theoperation of such swing.

A further object of the invention is to provide a swing which can beoccupied and operated at the same time by two or more children, thusadding to the enjoyment of use of the swing.

A further object of the invention is to produce a simple and inexpensiveohilds swing, and yet one which will be exceedingly effective for thepurpose for which it is designed.

These objects are accomplished by means of such structure and relativearrangement of parts as will full appear by a perusal of the followingspecification and claim.

In the drawings Fig. 1 is a perspective view of the swing.

Fig. 2 is a longitudinal sectional elevation of the swing.

Fig. 3 is an enlarged fragmentary transverse elevation, showing part ofthe actuating mechamsm.

Referring now more particularly to the characters of reference on thedrawings, the swing comprises a rectangular base I adapted to rest uponthe ground; such base including parallel side beams 2 connected adjacentthe ends by cross members 3.

The rectangular base I supports, in rigid relation, an upstanding,open-ended skeleton frame, indicated generally at 4. The skeleton frame4 includes vertical corner posts 5 merging with longitudinal top bars 6disposed in transversely spaced relation. The top bars 6 are connectedtogether by cross members I.

The swing unit is suspended from the upstanding frame 4 and comprisesthe following:

A pair of cross shafts 8 extend between the top bars 6 in spacedrelation lengthwise of the swing, and a pair of transversely spacedsuspension links 9 are secured to and depend from each of the crossshafts 8, corresponding suspension links 9 of the end pairs being alinedlengthwise of the swing.

A horizontal platform l0 extends lengthwise of the swing between thesuspension links 9, and the latter are pivotally connected, adjacenttheir lower ends, to stub shafts II fixed in connection with thehorizontal platform by means including transverse reinforcing irons l2afiixed to the bottom of said platform.

As so suspended the horizontal platform I!) is 2 capable of to-and-froswinging motion lengthwise of the swing.

Adjacent the center of the platform Ill the latter is fitted with seatsl3 disposed in facing, spaced-apart relation, and said seats aredisposed within a body It mounted on the platform Ill, and having afanciful configuration, such as an automobile, airplane, or boat; thelatter being illustrated in the present embodiment.

Between the seats I3 the horizontal platform It is formed with a centralopening I5, through which an upstanding operating lever I6 extends; saidlever being pivoted, intermediate its ends, as at I1, between a pair ofears I8 for to-andfro swinging motion in a longitudinal direction. Theupper end of the operating lever I6 is fitted with a transverse handlebar 9.

One pair of the transversely spaced suspension links 9 are extendeddownwardly below the corresponding stub shaft II as link extensions Zll,and an actuating link 2! connects between the lower end portion of theoperating lever l6 and a cross shaft 22 which is fixed in connectionwith, and extends between, the extensions 28; there being a bearing 23between said link 2! and shaft 22. The actuating link 2| is verticallyadjustably connected to the lever I6, while the cross shaft 22 issimilarly connected to the link extensions 29, whereby the effectivethrow of the described operating mechanism can be varied.

When the described swing is in use, children occupy the seats I3, graspthe handlebar l9 and swing the operating lever I6 to and fro, whichmotion is transmitted by the actuating link 2| through the cross shaft22 to the link extensions 29, to thus cause the entire assembly of thedevice to swing back and forth in a longitudinal direction; all to theamusement and exercise of the children.

From the foregoing description it will be readily seen that there hasbeen produced such a device as will substantially fulfill the objects ofthe invention, as set forth herein.

While this specification sets forth in detail the present and preferredconstruction of the device, still in practice such deviations from suchdetail may be resorted to as do not form a departure from the spirit ofthe invention, as defined by the appended claim.

Having thus described the invention the following is claimed as new anduseful, upon which Letters Patent are desired:

A swing comprising an upstanding main frame, longitudinally spaced pairsof transversely spaced 3 links pivoted on and depending from the mainframe, one pair of links being longer than the other, a platform, seatson the platform, a pair of laterally projecting trunnions on each end ofthe platform, one pair of trunnions being j0uI- naled in the lower endsof the shorter pair of links, and the other pair of trunnions beingjournaled in the longer pair of links at a point above their lower ends,a cross shaft extending between and rigidly secured to the lower ends of'said longer pair of links, a lever journaled substantially centrally ofand projecting below the plat form, a link pivoted at one end to thelower end of the lever, and a bearing on the other end of said lastnamed link, said shaft projecting freely through said bearing.
